Now that amrex::FFT exists, we can do the FFT to generate Gaussian random fields (e.g., for turbulence initial conditions and driving) directly on the GPU. Describe alternatives you've considered Keep using the existing Python script to generate the input turbulence field. Additional context AM...
先来看一个简单情况,不考虑random error term,也就是假设y=f(x)。Gaussian process的定义上就是说从这个随机过程任意取一些随机变量,他们服从多维正太分布,换句话说,f(x) 服从一个多维正太分布,f(x*)服从一个多维正太分布,(f(x)’,f(x*)’)’仍然服从多维正太分布,然后呢,多维正太分布有一个非常好的...

In this case, the CELL_COUNT field will show the number of cells within the polygon that have simulated values, and the number will be expressed as a negative value. This tool uses a random number generator in its operation. The Seed value used can be controlled in the Random number ...
Finally, compared to therandom field modelsdescribed in previous sections, these block based Gaussian mixture model may seem “incomplete” — providing only the marginal PDFs but not thejointPDF of the entire field,p(x). This issue can be resolved in two steps: first, we can find the cond...
RNA velocity is a standard method to estimate the velocity field in the gene expression space from scRNA-seq data, and it is also widely used to infer cell trajectories [56]. The comparison of the normalized speeds between cell velocity and RNA velocity showed that, despite some differences ...

The GP-LCCM is implemented in Python by using some blocks from: 1) the Gaussian Process Classifier (GPC) of the Scikit-Learn library (Pedregosa et al., 2011), which is based on Laplace approximation by Rasmussen and Williams (2006); 2) and lccm (El Zarwi, 2017a, El Zarwi, 2017b)...
We computed R2 for the masked predictions, repeating this experiment five times for random train–test splits. Predictions using the aligned coordinates from GPSA outperformed those using the original coordinates (Fig. 4e). We next asked whether downstream analyses of these data could be ...
